The new Vespa GTS 300 HPE models are equipped with a speed limiter. At 130km/h this intervenes in the on-board electronics and the engine speed / final speed is limited. Unfortunately, this already happens at real 120km/h.
With the Speed-Max ABS tone wheel the real speed is transmitted to the control unit by a changed sampling rate of the sensor. The limitation then starts at actual 130km/h and the vehicle reaches 10km/h more top speed.
The installation is easy. Remove the exhaust system, replace the old ABS tone ring with the new one, recalibrate the ASR system (instructions available for download), done.
